Fast.Done right.

I build websites you can configure yourself: launched in weeks, with clean code and tested quality.

What I do

I work fast without compromising quality: from structure to code that is easy to maintain.

  1. 01

    Speed

    Pages load in a fraction of a second: optimised images, minimal scripts, Core Web Vitals in the green.

  2. 02

    Fast delivery

    From brief to a working site in weeks: ready-made blocks, a clear plan and transparent stages with no surprises.

  3. 03

    Quality

    Typed code, tests and checks before every release. What ships works the same on a phone and on a big screen.

  4. 04

    Maintainability

    React, Next.js, TypeScript. Code that is easy to read and extend: nobody has to rewrite it from scratch after me.

  5. 05

    You run the site yourself

    Texts, blocks, pages, colours and menus are edited in a simple admin, no developer needed. Want it different? Drag a block and it is done.

Selected projects

Most of the work is under NDA, so instead of screenshots — what it does and the stack.

About me

Hi, I am Kyryl

I am a front-end developer: I build sites that launch fast, load fast and do not break after release.

Every site comes with a simple admin, so you change texts, pages and blocks yourself — without me and without waiting for a developer.

Experience

4+ years: from my first team to owning dozens of projects.

  1. IT company

    Front-end developer

    2022 — 2023 · 1.5 years

    • Introduced a new technology stack: the project scales easily and is simpler and cheaper to maintain.
    • Brought contract-first development between front-end and back-end: shared API contracts, fewer bugs, faster delivery.
    • Gained first hands-on experience with AWS: core services and integrating them into projects.
  2. Private client

    Developer

    2023 · 6 mo

    • Initiated and introduced design reviews: interface quality went up and the team got one design standard.
    • Built an AI support bot on Gemini: customer answers are automated and documentation is understood 40% better.
    • Set up CI/CD pipelines: code reaches production much faster and development speed grew by 30%.
  3. Freelance

    Turnkey websites

    2024 · 1 year

    • Ran projects on my own: from brief and estimate to launch and support.
    • Worked with clients directly — learned to hear the business, not just the spec.
    • Perfected launching sites fast without compromising on quality.
  4. Zagroza

    Front-end developer

    2025 — 2026 · 1 year

    • Initiated the adoption of new technologies in the team and took them to production.
    • Gained extensive experience with page builders: sites that clients configure themselves, without a developer.
    • Built fully responsive sites — from the smallest phones to large monitors.
    • Was responsible for many projects in parallel: from estimate and architecture to launch and support.
    • Understood what the business needs and was actively involved in development at every stage.

AI approach

Fast, not sloppy

AI speeds up the routine, and I own every decision.

  1. Harnesses

    I work through agent harnesses: the AI gets clear context, limits and checks instead of free-form generation.

  2. My own cases

    I regularly test models on my own tasks and use the one that handles my code best.

  3. Code under control

    I read and check every line. The AI speeds things up, the responsibility for the result is mine.

My principles

  1. Speed

    Core Web Vitals in the green

    A fast site saves advertising money: people neither wait nor leave. That is why I measure load time from day one, not at the end.

  2. Quality

    Checked before every release

    I do not hand over work until I have checked it myself: types, tests, different devices and browsers. Bugs are better found before launch than after.

  3. Freedom

    The site is in your hands

    You do not depend on me after launch: the admin is simple, the blocks are flexible, and the code and access belong to you. Want to change a page — it takes a minute.

  4. Openness

    Weekly demos

    Once a week I show what is done and share a link to the working version. You always know where the project stands and how much is left.
